How to Find Out Who Owns a Business, by Entity Type

Every business is registered somewhere, but "somewhere" isn't the same for every entity type. LLCs and corporations file with a state's Secretary of State or equivalent office. Sole proprietors operating under a name other than their own legal name file a DBA (doing business as) or fictitious name registration, often with a county clerk instead of the state. Nonprofits file annual returns with the IRS. Treating all of these as one generic "business lookup" is why so many general guides end up vague — the useful answer only shows up once you know which record you're actually searching.

Every state runs a free, public business entity search covering LLCs and corporations registered there. Search the company by name and its detail page will show its status, entity number, and registered agent's name and address — the same lookup this site covers for every state.

Where it gets less certain is ownership specifically. A registered agent is a required legal point of contact, not necessarily an owner — some states also list managers or officers, but many don't require member or shareholder names on the public filing at all. For LLCs specifically, see this site's dedicated guide on finding out who owns an LLC for the deeper walk-through, including what to do when a state's search comes back with only a registered agent.

For corporations, be realistic about what's actually public: officers and directors are sometimes listed with the state, but the shareholder register — who actually owns the stock — is a private company record. Existing shareholders have a legal right to inspect it; the general public doesn't. The exception is publicly traded companies, where major shareholders show up in SEC filings (like proxy statements and Schedule 13D/13G filings) instead of anything a state's entity search will ever surface.

A sole proprietor doing business under a name that isn't their own legal name — "Jane Smith" operating as "Riverside Bookkeeping," for example — is usually required to file a DBA (doing business as) or fictitious business name registration, typically with the county clerk or the state, depending on where the business operates. Unlike an LLC filing, which can list a registered agent instead of an owner, a DBA filing exists specifically to tie a trade name back to the real person or entity behind it, so it usually names the owner directly. For a small, local, one-owner business, checking for a DBA filing is often faster and more conclusive than searching an entity registry.

A nonprofit's state filing (often a simple annual or biennial report, similar to what LLCs file) usually says very little about who runs the organization. The real record is its IRS Form 990 — the annual information return that most tax-exempt nonprofits are required to file, and which is public by law. Form 990s list officers, directors, and key employees by name, often with compensation figures attached, and are searchable for free through ProPublica's Nonprofit Explorer or Candid's 990 finder, without needing to know which state the organization filed in.

Many LLCs and corporations were required to report their beneficial owners to FinCEN, a federal agency, under the Corporate Transparency Act. It's tempting to assume this means beneficial ownership is a public lookup — it isn't. That FinCEN database is restricted to law enforcement, certain financial institutions, and other authorized users; it was never built as a public search tool, and there's no public-facing lookup for it. It also no longer covers most U.S. companies at all. See this site's guide on beneficial ownership information reporting for who's actually required to file today.

This is the most common dead end in an LLC or corporation search: the entity detail page shows a registered agent's name — sometimes a commercial service like Northwest Registered Agent or CT Corporation — instead of an owner. That's not a failed search; it means the state doesn't require owner names on the public filing, and the entity used a commercial agent rather than an individual. From there, a public records request to the state (some states hold additional filing details not shown in the online search), a domain WHOIS lookup if the business has a website, or checking for a separate DBA filing are the next reasonable steps.

Can I find out who owns a private corporation?

Not directly in most cases. A state's entity search may list officers or directors, but shareholder ownership of a privately held corporation isn't public record — that right belongs to existing shareholders, not the general public. Publicly traded companies are the exception, since major shareholders show up in SEC filings instead.

Is the federal beneficial ownership (BOI) database open to the public?

No. FinCEN's beneficial ownership database is restricted to law enforcement and certain authorized institutions, and as of August 2026 it no longer covers U.S.-formed companies at all — it was never set up as a public lookup tool to begin with.

Why does a business entity search only show a registered agent instead of an owner?

A registered agent is a required legal point of contact for the entity, not an ownership listing — many states don't require member, manager, or shareholder names on the public filing at all, so a registered agent is often the only name that shows up.

What's the fastest way to find who owns a small local business?

Check whether it operates under a DBA or fictitious business name — that filing usually names the actual owner directly and tends to resolve faster than a state entity search, which may only show a registered agent for an LLC or corporation.
